Concerning putting your rack-mounted equipment an additional 0.8m above the floor: Clause 7.2 also says that this arrangement must be safe. If the 0.8m support is too small in area, the test setup would violate this requirement.
The clause also says that this setup may be done if specifically required by the product committees (my paraphrase). Is this the case with your testing?
